How to use our heat resistant firebrick mix

Add water slowly, mixing with a trowel until a dry crumbly paste is obtained.

Add more water slowly until mix is a pliable ball.

On a clean flat surface mould to the size & shape brick required. Trim with a knife if necessary.

Clean area to be filled removing any loose material and dust. Then wet the area with water.

Place brick in firmly to take up vacant space.

Air dry for 24 hours. Then heat set with a small gentle fire. Your unit is then ready for normal use.

Safety

Never use petrol, oil or kerosene to help light the fire as they can cause an explosion.

If you have young children - a guard around any form of heating is a good precaution - Ask your dealer for advice on the best type.

Smoke detectors save lives. With or without a fireplace, a smoke detector is a good investment in your family’s safety.

Getting Started

Use kindling wood, paper and fire lighters to get the fire started. Large pieces of wood should be added after a bed of hot coals has been established.

Leave air controls open for 20 - 30 minutes to start the fire burning. You can expect some smoke from your flu when you first start but it should not last longer than 15 minutes.

Fueling your Fire

It’s important to get the fire hot as quick as possible & maintain it for the heating period.

Most heaters burn better with 3 or 4 logs rather than 1 or 2. Logs should not be too big -- 2kg to 4 kg or 40cm logs are typical.

Heaters with grates will perform better with a layer of ash on the base of the firebox, and should only need cleaning periodically. When cleaning out the ash, always leave 10mm or so behind.

Efficient burning only occurs when adequate air is supplied to the fuel. Leave air controls on for 15 - 20 minutes after reloading.

Overnight Burning

For overnight burning, load the heater at least half an hour before going to bed. Only turn the air supply down to a minimum once all the wood is charred (about 15 - 20 minutes).

Most heaters should still burn for eight hours without difficulty and you will have far less creosote problems than if you fill the heater and turn it to slow burn straight away.

It will probably take you some time to get the feel of operating your heater for long periods. You might even find that once you have a good lighting method worked out and your house is well insulated you don’t need to burn overnight except on the coldest nights.

Do not close down air supply totally overnight - a little air avoids a lot of smoke.

Buying Fuel

It is always best, to use the type of fuel recommended by the manufacturer. If your heater meets the national emission standards, it will have a compliance plate which specifies the correct fuel to use.

Be sure of what you are buying or collecting in firewood.

Money Saving

Getting the best performance from your fuel and heater will save you money each year.

Make your home energy efficient by insulating the ceilings and walls.

Prevent heat leaks through cracks in doors and windows.

Reduce heat loss through windows by drawing heavy curtains at night.

Leaving the firebox open will affect the efficiency and reduce the heat output of your heater.

Wood Storage

Buy your wood in Spring or Summer as heaters operate best when wood is completely dry and well seasoned.

Store wood undercover in a dry ventilated area. Wood stored on pallets in a crisscrossed fashion allows air to circulate freely.

Service and Maintenance

The key to clean and efficient heating is not just installing an efficient heater, it is also operating and maintaining it correctly.

Whatever the age of your heater, use it correctly to reduce the need for repairs and servicing. Every heater has slightly different characteristics, so read and follow any instructions from the manufacturer carefully.

Service your heater during Spring or early Summer. This minimizes the corrosive effects of creosote residues and condensation during the off season.

Prior to winter, check the condition of the heater including the flu, door, seals and baffles. Specifically check for bird nests in or near the flu systems in the roof cavity. If loose insulation has been added to the ceiling check carefully that none has built up in the flu cavity clearance area. Alternatively, have an experienced service person to do these checks.

Flues should be checked regularly by a chimney sweep.

Make it a habit to look outside and check your flu for smoke.

Richard from Hughes Brothers Engineering, Yatala Qld has made this awesome potbelly stove for his wife Marie's birthday party from scraps from the cranes he repairs. Marie was kind enough to send us a few pictures of the finished product. Richard has used our Hi-T Potbelly Black Paint to paint the steel and then used our Instant Brick to make bricks to add to the inside of the Potbelly stove. We think Richard is very clever and has done a wonderful job and his wife Marie is very proud. Thanks for sharing Marie
